AMD board partner PowerColor's website briefly showed product categories for graphics cards based on the upcoming Radeon RX 6600 XT and Radeon RX 6600 graphics processors. This would mean that a formal launch of the two is just around the corner. Both SKUs are reportedly based on the 7 nm "Navi 23" silicon. The RX 6600 XT maxes it out, featuring 2,048 stream processors, while the RX 6600 is slightly cut down, in featuring 1,792 of them. The "Navi 23" silcon is based on the same RDNA2 graphics architecture as the rest of the RX 6000 series, which means DirectX 12 Ultimate support, including raytracing. Both feature 8 GB of video memory, whereas the RX 6600 also comes in 4 GB. Both memory options use 16 Gbps GDDR6 memory, over a 128-bit wide memory bus. PowerColor is expected to design a variety of custom-design products based on the two.
